Question

The difference in angular momentum associated with the electron in the two successive orbits of hydrogen atom is

• A. $\frac{h}{\pi}$
• B. $\frac{h}{2\pi}$
• C. $\frac{h}{2}$
• D. $(n-1)$ $\frac{h}{2\pi}$

Answer 1

Answer: (B)

$\frac{h}{2\pi}$

Answer 2

$L_n = nh / 2 \pi$. Hence $L_{n + 1} - L_n = h/2 \, \pi$.
